Does sound like the cam phaser. Then again could also be the chain guides with the timing chain bouncing off of them. A trade in might be in order or a cost estimate to replace guides and such. Then you figure it out.
I have seen quite a few 2000 4.0 Fords with noisy engines. Run them long enough and it should get real noisy, run ratty and then go poof.
